Question about 1995 Jeep Wrangler

Tapping nosie in lower crankcase when starting 2.5L engine

This problem just started on my 1995 Jeep 2.5L YJ (120,000 Miles). It is a tapping sound that starts when I first start the jeep. The sound goes away after the jeep warms up. But, if turn the jeep off for 15 min. The sound is back again. I have located the sound in the back/bottom rear crankcase/oil pan. Anyone had this issue before. Also I had a 1975 Jeep CJ where the rod bearings started to go bad, but they did not sound like this. The sound just got worse until the engine failed. Thanks

Probably just a hydralic lifter tapping when cold. Change the oil in it and let it warm up before taking off. Be sure and use the correct oil, 10w/30 or whatever the manual says for your climate.

I have a 2001 ford focus that has a tapping sound coming from the engine. 120,000 miles and the oil is full


Hi when was the last oil & filter change, what engine is it as it will have 2 specific oil types to use, and you need to use the right one for the miles it has done. also when was the timing last checked or changed. there are oil additives that can be used on warn engines. if the engine is more tapping when cold or hot or even no change in temps. How To Quiet any Noisy Engine Valves Lifters or Bearings you can use this type of additives but when you start to use them its best to keep using them. if you have an engine rebuild it would not be recommended to use these.

2002 grand cherokee engine tapping loudly


My first guess would be a failing valve lifter. They can become weak with age and not able to hold oil pressure.
Especially in an engine with that many miles on the clock.
If the noise is constant you may be able to find out which cylinder by running a compression test. maybe.

check with a scan tool for any trouble codes, possibly the o2 sensors are gone, the tapping is a lubrication problem try to clean the mesh on the crankcase or a engine cleaning procedure.

Why does my jeep have a hard time starting in the mornings when its cold out (35 to 40 degrees)it has a new tune up, 120,000 miles and a 4cyl engine


My guess would be the battery. When was the last time it was replaced or serviced.
Batteries are rated in CCA (Cold Cranking Amps). When it is cold out the battery has to work harder to start the Jeep, in addition to battery having lower Amperage.
So your battery might not have enough CCAs to turn the Jeep over on those cold mornings.
